The prokaryote that is credited with construction of the first recombinant DNA by linking an antibiotic resistance gene with its native plasmid is

How does beta -galactosidase coding sequence act as a selectable marker ? Why is it a preferred selectable marker to antibiotic resistance genes ? Explain.

Study the following statements regarding recombinant DNA technology and select the incorrect ones. (i) Taq polymerase extends the primers using the nucleotides provided in the reaction. (ii) Antibiotic resistance genes are considered as desirable genes in recombinant DNA technology. (iii) DNA fragments are separated according to their charge only, in agarose gel electrophoresis. (iv) Transformation is a procedure through which a piece of DNA is integrated in to the genome of a host bacterium. (v) To produce higher yields of a desired protein, host cells can be multiplied in a continuous culture. (vi) Downstream processing is one of the steps of polymerase chain reaction.
